I have four. I created one on SL long ago, maybe in 2009. I created a second avatar when I started up my own grid a few years ago. Then I created the third one on kitely to act as an outside avatar to help me debug my own grid. And finally, I recently created an avatar, also on my own grid, to test Corrade.
The first three all look about the same, and have the same first name, the last one is very different since I may not be in total control of it as some point in the future.
